The ideal gas equation is PV = nRT, where P is pressure, V is volume, n is the number of moles, R is a constant, and T is temperature. You are told that a sample of gas has a pressure of P = 893 torr, a volume of V = 3360 mL, and a temperature of T = 298 K. If you use R = 8.206 × 10^−2 L⋅atm/(K⋅mol), which of the following conversions would be necessary before you could find the number of moles of gas, n, in this sample? Check all that apply.
